My 9yr old son bit himself in school. I noticed his bite marks on his arms when he was getting out of the shower the other night and asked him what happenned to him, he replied that he bit him self to release his anger because his teacher made him do an assignment twice. I told him that was not cool and that we would talk about this later. I have not started the conversation about it because I don't know how to approach the issue. Please help, any suggestions?
Best,
Sof
